Place each spkr ~2,4 from its adjacent side wall (that's woofer centre to side wall). This is a starting for narrow, long rooms with spkrs firing down the long side.
Best, however, is to FIRST determine the distance fm the back wall. Move one spkr into the room & check the midbass energy -- I expect this to be b/ween 5-7' into the room. WHen that's OK, fine tune to achieve clarity in the upper bass/bass region. Then place the spkrs relative to side walls.
The trick for knowing when you have good placement is when you feel energy in the music. Then minor adjustments make a major sonic difference.
REMEMBER, being so close to side wall will require toe-in to avoid 1st reflections as much as possible.
